Macbook A1466 820-3437 3v42 Short

[Instafixx]

Device came in as not charging.
PP3V42 was shorted. PPBUS was 0V with no Shorts.
Injected Voltage and SMC was heating up. Replace the SMC.
Now i get 8.2V at PPBUS and i get 3.4V at 3V42 but still no Mgsafe light and not turning on.

PM_SLP_S4_L and ALLSYSPWRGD are missing.

Incorrect PPBUS_G3H voltage; probably no communication between SMC and U7100.

Check SMC's basic voltages and signals; already mentioned various times on the forum.
